Intrinsic decoherence and classical-quantum correspondence in two coupled delta-kicked rotors

We show that classical-quantum correspondence of center of mass motion in two coupled delta-kicked rotors can be obtained from intrinsic decoherence of the system itself which occurs due to the entanglement of the center of mass motion to the internal degree of freedom without coupling to external environment

Produção E Composição Mineral Do Coentro Em Sistema Hidroponico De Baixo Custo

Coriander (Coriandrum sativum L.) is a vegetable widely consumed in Brazil, however, especially in communities across the Brazilian semiarid, it is still cultivated in a rudimentary way, without rationalization of inputs such as seeds and fertilizers. So the objective of this study was to evaluate the impacts of strategies of optimization of inputs and their implications in the production and mineral composition of coriander (cv. Tabocas) grown in low-cost hydroponic system. The treatments consisted of four rates of seeds per cell in seeding (0.5, 1.0, 1.5 and 2.0 g) and three spacing between cells (7.0, 10.0 and 15.0 cm), distributed in a completely randomized design, analyzed in 4×3factorial, with three repetitions, totaling 36 experimental units. The fresh and dry weight of plant, shoot and root, as well as content of Ntot, P, K, Ca, Mg, Cl and Na in the shoot were evaluated, and the results were submitted to analysis of variance. It was concluded that the production of coriander is feasible in the " low cost hydroponic module ". It is recommended the use of 1.0 g of seeds per cell and spacing of 7.0 cm between cells, which means an average production of 5.5 kg m-2 of fresh mass of aerial parts. About the mineral composition, it was found a decreasing trend of Ca and chlorides contents due to the increase in seed weight. © 2016, Universidade Estadual Paulista - UNESP.

A "cookbook" for vulnerability research

There is a growing need to facilitate the interdisciplinary study of the relationship between the environment and human health and well-being. It is increasingly recognized that vulnerability is a key construct allowing discipline-specific research questions on these topics to be meaningfully contextualized. However, there is little consensus regarding the meaning of the concept of vulnerability or how it can best be utilized in research studies. In this perspective article, we use the metaphor of a "cookbook" to review promising trends in vulnerability research and to make this body of research accessible to a multi-disciplinary audience. Specifically, we discuss a selection of "recipes" (theoretical frameworks), "ingredients" (vulnerability domains), "cooking tools" (qualitative and quantitative methods), and approaches to "meal presentation" (communication of results) drawn from vulnerability studies published in the past 15 years. Our aim is for this short "cookbook" to serve as a jumping-off point for scholars unfamiliar with the vulnerability literature and an inspiration for scholars more familiar with this topic to develop new ways to navigate the tension between locally-specific assessments of vulnerability and attempts at standardization. Our ultimate take-home message is that the specifics theories and methods used in vulnerability research are less important than attention to what we see as the 3 'T's of transparency, triangulation, and transferability, and to efforts to make vulnerability research both "place-based" and comparable

Whipple's Disease With Neurological Manifestations: Case Report

Whipple's disease (WD) is an uncommon multisystem condition caused by the bacillus Tropheryma whipplei. Central nervous system involvement is a classical feature of the disease observed in 20 to 40% of the patients. We report the case of a 62 yeards old man with WD that developed neurological manifestations during its course, and discuss the most usual signs and symptoms focusing on recent diagnostic criteria and novel treatment regimens.622 A342346Whipple, G.H., A hitherto undescribed disease characterized anatomically by deposits of fat and fatty acids in the intestinal and mesenteric lymphatic tissues (1907) Johns Hopkins Hosp Bull, 18, pp. 382-391Marth, T., Raoult, D., Whipple's disease (2003) Lancet, 36, pp. 239-246Gerard, A., Sarrot-Reynauld, F., Liozon, E., Neurologic presentation of Whipple disease: Report of 12 cases and review of the literature (2002) Medicine (Baltimore), 81, pp. 443-457Brown, A.P., Lane, J.C., Murayama, S., Vollmer, D.G., Whipple's disease presenting with isolated neurological symptoms: Case report (1990) J Neurosurg, 73, pp. 623-627Bostwick, D.G., Bensch, K.G., Burke, J.S., Whipple's disease presenting as aortic insufficiency (1981) N Engl J Med, 305, pp. 995-998Raoult, D., A febrile, blood culture-negative endocarditis (1999) Ann Intern Med, 131, pp. 144-146Chan, R.Y., Yannuzzi, L.A., Foster, C.S., Ocular Whipple's disease: Earlier definitive diagnosis (2001) Ophthalmology, 108, pp. 2225-2231Louis, E.D., Lynch, T., Kaufmann, P., Fahn, S., Odel, J., Diagnostic guidelines in central nervous system Whipple's disease (1996) Ann Neurol, 40, pp. 561-568Sieracki, J.C., Whipple's disease: Observations on systemic involvement (1958) Amer Med Asso Arch Pathol, 66, pp. 464-467Anderson, M., Neurology of Whipple's disease (2000) J Neurol Neurosurg Psychiatry, 68, pp. 2-5De Coene, B., Gilliard, C., Indekeu, P., Whipple's disease confined to the central nervous system (1996) Neuroradiology, 38, pp. 325-327Verhagen, W.I.M., Huygen, P.L.M., Dalman, J.E., Schuurmans, M.M.J., Whipple's disease and the central nervous system: A case report and a review of the literature (1996) Clin Neurol Neurosurg, 98, pp. 299-304Feldman, M., Hendler, R.S., Morrison, E.B., Acute meningoencephalitis after withdrawal of antibiotics in Whipple's disease (1980) Ann Intern Med, 93, pp. 709-711Schwartz, M.A., Selhorst, J.B., Ochs, A.L., Oculomasticatory myorhythmia: A unique movement disorder occurring in Whipple's disease (1986) Ann Neurol, 20, pp. 677-683Manzel, K., Tranel, D., Cooper, G., Cognitive and behavioral abnormalities in a case of central nervous system Whipple disease (2000) Arch Neurol, 57, pp. 399-403Halperin, J.J., Landis, D.M., Kleinman, G.M., Whipple's disease of the nervous system (1982) Neurology, 32, pp. 612-617Feurle, G.E., Volk, B., Waldherr, R., Cerebral Whipple's disease with negative jejunal histology (1979) N Engl J Med, 300, pp. 907-908Madoule, P., Ciaudio-Lacroix, C., Halimi, P., Osteoarticular lesions in Whipple's disease, a propos of a destructive form and review of the literature (1985) J Radiol, 66, pp. 345-350Brändle, M., Ammann, P., Spinas, G.A., Relapsing Whipple's disease presenting with hypopituitarism (1999) Clin Endocrinol, 50, pp. 399-403Topper, R., Gartung, C., Block, F., Neurologic complications in inflammatory bowel diseases (2002) Nervenarzt, 73, pp. 489-499Clarke, C.E., Falope, Z.F., Abdelhadi, H.A., Cervical myelopathy caused by Whipple's disease (1998) Neurology, 50, pp. 1505-1506Ramzan, N.N., Loftus, E., Burgart, L.J., Diagnosis and monitoring of Whipple disease by polymerase chain reaction (1997) Ann Intern Med, 126, pp. 520-527Von Herbay, A., Ditton, H.J., Scuhmacher, F., Whipple's disease: Staging and monitoring by cytology and polymerase chain reaction analysis of cerebrospinal fluid (1997) Gastroenterology, 113, pp. 434-441Kremer, S., Besson, G., Bonaz, B., Pasquier, B., Le Bas, J.F., Grand, S., Diffuse lesions in the CNS revealed by MR imaging in a case of Whipple disease (2001) Am J Neuroradiol, 22, pp. 493-495Romanul, F.C., Radvany, J., Rosales, R.K., Whipple's disease confined to the brain: A case studied clinically and pathologically (1977) J Neurol Neurosurg Psychiatry, 40, pp. 901-909Thompson, D.G., Leidingham, J.M., Howard, A.J., Brown, C.L., Meningitis in Whipple's disease (1978) BMJ, 2, pp. 14-15Feurle, G.E., Marth, T., An evaluation of antimicrobial treatment for Whipple's disease: Tetracycline versus trimethoprim-sulfamethoxazole (1994) Dig Dis Sci, 39, pp. 1642-1648Misbah, S.A., Mapstone, N.P., Whipple's disease revisited (2000) J Clin Pathol, 53, pp. 750-755Schnider, P.J., Reisinger, E.C., Berger, T., Krejs, G.J., Auff, E., Treatment guidelines in central nervous system Whipple's disease (1997) Ann Neurol, 41, pp. 561-56

Environment-Induced Decoherence and the Transition From Quantum to Classical

We study dynamics of quantum open systems, paying special attention to those aspects of their evolution which are relevant to the transition from quantum to classical. We begin with a discussion of the conditional dynamics of simple systems. The resulting models are straightforward but suffice to illustrate basic physical ideas behind quantum measurements and decoherence. To discuss decoherence and environment-induced superselection einselection in a more general setting, we sketch perturbative as well as exact derivations of several master equations valid for various systems. Using these equations we study einselection employing the general strategy of the predictability sieve. Assumptions that are usually made in the discussion of decoherence are critically reexamined along with the ``standard lore'' to which they lead. Restoration of quantum-classical correspondence in systems that are classically chaotic is discussed. The dynamical second law -it is shown- can be traced to the same phenomena that allow for the restoration of the correspondence principle in decohering chaotic systems (where it is otherwise lost on a very short time-scale). Quantum error correction is discussed as an example of an anti-decoherence strategy. Implications of decoherence and einselection for the interpretation of quantum theory are briefly pointed out.Comment: 80 pages, 7 figures included, Lectures given by both authors at the 72nd Les Houches Summer School on "Coherent Matter Waves", July-August 199
